"It all began one morning last July when we noticed a young manof twenty-six crying in his bed in Dr. Pitre's ward. He had just come from a longjourney on foot and was exhausted, but that was not the cause of his tears. He weptbecause he could not prevent himself from departing on a trip when the need tookhim; he deserted family, work, and daily life to walk as fast as he could, straightahead, sometimes doing 70 kilometers a day on foot, until in the end he would bearrested for vagrancy and thrown in prison."

--Dr.Philippe Tissie, July 1886

Thus begins therecorded case history of Albert Dadas, a native of France's Bordeaux region and thefirst diagnosed mad traveler, or fuguer. An occasional employee of a local gascompany, Dadas suffered from a strange compulsion that led him to travelobsessively, often without identification, not knowing who he was or why hetraveled. He became notorious for his extraordinary expeditions to such far-reachingspots as Algeria, Moscow, and Constantinople. Medical reports of Dadas set off atthe time of a small epidemic of compulsive mad voyagers, the epicenter of which wasBordeaux, but which soon spread throughout France to Italy, Germany, andRussia.

Today we are similarly besieged by mentalillnesses of the moment, such as chronic fatigue syndrome and attention deficithyperactivity disorder. The debate rages about which of these conditions areaffectations or cultural artifacts and which are "real." In Mad Travelers, IanHacking uses the Dadas case to weigh the legitimacy of cultural influences versusphysical symptoms in the diagnosis of psychiatric disorders. He argues thatpsychological symptoms find stable homes at a given place and time, in "ecologicalniches" where transient illnesses flourish.

Usingthe records of Dadas's physician, Philippe Tissie, Hacking attempts to make sense ofthis strange epidemic. While telling his fascinating tale, he raises probingquestions about the nature of mental disorders, the cultural repercussions of theirdiagnosis, and the relevance of this century-old case study for today's overanalyzedsociety.

A good book may have the power to change the way we see the world, but a great book actually becomes part of our daily consciousness, pervading our thinking to the point that we take it for granted, and we forget how provocative and challenging its ideas once were-and still are. "The Structure of Scientific Revolutions" is that kind of book. When it was first published in 1962, it was a landmark event in the history and philosophy of science. And fifty years later, it still has many lessons to teach. With "The Structure of Scientific Revolutions", Kuhn challenged long-standing linear notions of scientific progress, arguing that transformative ideas don't arise from the day-to-day, gradual process of experimentation and data accumulation, but that revolutions in science, those breakthrough moments that disrupt accepted thinking and offer unanticipated ideas, occur outside of "normal science," as he called it. Though Kuhn was writing when physics ruled the sciences, his ideas on how scientific revolutions bring order to the anomalies that amass over time in research experiments are still instructive in our biotech age. This new edition of Kuhn's essential work in the history of science includes an insightful introductory essay by Ian Hacking that clarifies terms popularized by Kuhn, including paradigm and incommensurability, and applies Kuhn's ideas to the science of today. Usefully keyed to the separate sections of the book, Hacking's essay provides important background information as well as a contemporary context. Newly designed, with an expanded index, this edition will be eagerly welcomed by the next generation of readers seeking to understand the history of our perspectives on science.

Gambling on God brings together a superb collection of new and classic essays that provide the first sustained analysis of Pascal's Wager and the idea of an infinite utility as well as the first in-depth look at moral objections to the Wager.

One of Ian Hacking's earliest publications, this book showcases his early ideas on the central concepts and questions surrounding statistical reasoning. He explores the basic principles of statistical reasoning and tests them, both at a philosophical level and in terms of their practical consequences for statisticians. Presented in a fresh twenty-first-century series livery, and including a specially commissioned preface written by Jan-Willem Romeijn, illuminating its enduring importance and relevance to philosophical enquiry, Hacking's influential and original work has been revived for a new generation of readers.

This truly philosophical book takes us back to fundamentals - the sheer experience of proof, and the enigmatic relation of mathematics to nature. It asks unexpected questions, such as 'what makes mathematics mathematics?', 'where did proof come from and how did it evolve?', and 'how did the distinction between pure and applied mathematics come into being?' In a wide-ranging discussion that is both immersed in the past and unusually attuned to the competing philosophical ideas of contemporary mathematicians, it shows that proof and other forms of mathematical exploration continue to be living, evolving practices - responsive to new technologies, yet embedded in permanent (and astonishing) facts about human beings. It distinguishes several distinct types of application of mathematics, and shows how each leads to a different philosophical conundrum. Here is a remarkable body of new philosophical thinking about proofs, applications, and other mathematical activities.

This is a volume of specially commissioned essays of analytical philosophy, on topics of current interest in ethics and the philosophy of logic and language. Among the topics discussed are the making of wicked promises, G. E. Moore's early ethical views, as well as indexicals, tense, indeterminism, conventionalism in mathematics, and identity and necessity. The essays are all by former students of Casimir Lewy, until recently Reader in Philosophy at the University of Cambridge and an exponent of a particularly thoroughgoing form of philosophical analysis. Together, they represent some of the best work in these areas at present, and express what may be described as a characteristic 'Cambridge' voice.

Historical records show that there was no real concept of probability in Europe before the mid-seventeenth century, although the use of dice and other randomizing objects was commonplace. Ian Hacking presents a philosophical critique of early ideas about probability, induction, and statistical inference and the growth of this new family of ideas in the fifteenth, sixteenth, and seventeenth centuries. Hacking invokes a wide intellectual framework involving the growth of science, economics, and the theology of the period. He argues that the transformations that made it possible for probability concepts to emerge have constrained all subsequent development of probability theory and determine the space within which philosophical debate on the subject is still conducted. First published in 1975, this edition includes an introduction that contextualizes his book in light of developing philosophical trends. Ian Hacking is the winner of the Holberg International Memorial Prize 2009.

This is an introductory textbook on probability and induction written by one of the world's foremost philosophers of science. The book has been designed to offer maximal accessibility to the widest range of students (not only those majoring in philosophy) and assumes no formal training in elementary symbolic logic. It offers a comprehensive course covering all basic definitions of induction and probability, and considers such topics as decision theory, Bayesianism, frequency ideas, and the philosophical problem of induction. The key features of the book are: * A lively and vigorous prose style* Lucid and systematic organization and presentation of the ideas* Many practical applications* A rich supply of exercises drawing on examples from such fields as psychology, ecology, economics, bioethics, engineering, and political science* Numerous brief historical accounts of how fundamental ideas of probability and induction developed.* A full bibliography of further reading Although designed primarily for courses in philosophy, the book could certainly be read and enjoyed by those in the social sciences (particularly psychology, economics, political science and sociology) or medical sciences such as epidemiology seeking a reader-friendly account of the basic ideas of probability and induction. Ian Hacking is University Professor, University of Toronto. He is Fellow of the Royal Society of Canada, Fellow of the British Academy, and Fellow of the American Academy of Arts and Sciences. he is author of many books including five previous books with Cambridge (The Logic of Statistical Inference, Why Does Language Matter to Philosophy?, The Emergence of Probability, Representing and Intervening, and The Taming of Chance).

In this important new study Ian Hacking continues the enquiry into the origins and development of certain characteristic modes of contemporary thought undertaken in such previous works as his best selling Emergence of Probability. Professor Hacking shows how by the late nineteenth century it became possible to think of statistical patterns as explanatory in themselves, and to regard the world as not necessarily deterministic in character. Combining detailed scientific historical research with characteristic philosophic breath and verve, The Taming of Chance brings out the relations among philosophy, the physical sciences, mathematics and the development of social institutions, and provides a unique and authoritative analysis of the "probabilization" of the Western world.

A lively and clearly written introduction to the philosophy of natural science, organized around the central theme of scientific realism.

This book is a philosophical study of the basic principles of statistical reasoning. Professor Hacking has sought to discover the simple principles which underlie modern work in mathematical statistics and to test them, both at a philosophical level and in terms of their practical consequences fort statisticians. The ideas of modern logic are used to analyse these principles, and results are presented without the use of unfamiliar symbolism. It begins with a philosophical analysis of a few central concepts and then, using an elementary system of logic, develops most of the standard statistical theory. the analysis provides answers to many disputed questions about how to test statistical hypotheses and about how to estimate quantities in the light of statistical data. One product of the analysis is a sound and consistent rationale for R. A. Fisher's controversial concept of 'fiducial probability'.

Many people find themselves dissatisfied with recent linguistic philosophy, and yet know that language has always mattered deeply to philosophy and must in some sense continue to do so. Ian Hacking considers here some dozen case studies in the history of philosophy to show the different ways in which language has been important, and the consequences for the development of the subject. There are chapters on, among others, Hobbes, Berkeley, Russell, Ayer, Wittgenstein, Chomsky, Feyerabend and Davidson. Dr Hacking ends by speculating about the directions in which philosophy and the study of language seem likely to go. The book will provide students with a stimulating, broad survey of problems in the theory of meaning and the development of philosophy, particularly in this century. The topics treated in the philosophy of language are among the central, current concerns of philosophers, and the historical framework makes it possible to introduce concretely and intelligibly all the main theoretical issues.

It asks unexpected questions, such as 'what makes mathematics mathematics?', 'where did proof come from and how did it evolve?', and 'how did the distinction between pure and applied mathematics come into being?'

Lost in the raging debate over the validity of social construction is the question of what, precisely, is being constructed. Facts, gender, quarks, reality? Is it a person? An object? An idea? A theory? Each entails a different notion of social construction, Ian Hacking reminds us. His book explores an array of examples to reveal the deep issues underlying contentious accounts of reality. Especially troublesome in this dispute is the status of the natural sciences, and this is where Hacking finds some of his most telling cases, from the conflict between biological and social approaches to mental illness to vying accounts of current research in sedimentary geology. He looks at the issue of child abuse--very much a reality, though the idea of child abuse is a social product. He also cautiously examines the ways in which advanced research on new weapons influences not the content but the form of science. In conclusion, Hacking comments on the "culture wars" in anthropology, in particular a spat between leading ethnographers over Hawaii and Captain Cook. Written with generosity and gentle wit by one of our most distinguished philosophers of science, this wise book brings a much needed measure of clarity to current arguments about the nature of knowledge.

With the unusual clarity, distinctive and engaging style, and penetrating insight that have drawn such a wide range of readers to his work, Ian Hacking here offers his reflections on the philosophical uses of history. The focus of this volume, which collects both recent and now-classic essays, is the historical emergence of concepts and objects, through new uses of words and sentences in specific settings, and new patterns or styles of reasoning within those sentences. In its lucid and thoroughgoing look at the historical dimension of concepts, the book is at once a systematic formulation of Hacking's approach and its relation to other types of intellectual history, and a valuable contribution to philosophical understanding.

Hacking opens the volume with an extended meditation on the philosophical significance of history. The importance of Michel Foucault--for the development of this theme, and for Hacking's own work in intellectual history--emerges in the following chapters, which place Hacking's classic essays on Foucault within the wider context of general reflections on historical methodology. Against this background, Hacking then develops ideas about how language, styles of reasoning, and "psychological" phenomena figure in the articulation of concepts--and in the very prospect of doing philosophy as historical ontology.

Twenty-five years ago one could list by name the tiny number of multiple personalities recorded in the history of Western medicine, but today hundreds of people receive treatment for dissociative disorders in every sizable town in North America. Clinicians, backed by a grassroots movement of patients and therapists, find child sexual abuse to be the primary cause of the illness, while critics accuse the "MPD" community of fostering false memories of childhood trauma. Here the distinguished philosopher Ian Hacking uses the MPD epidemic and its links with the contemporary concept of child abuse to scrutinize today's moral and political climate, especially our power struggles about memory and our efforts to cope with psychological injuries.

What is it like to suffer from multiple personality? Most diagnosed patients are women: why does gender matter? How does defining an illness affect the behavior of those who suffer from it? And, more generally, how do systems of knowledge about kinds of people interact with the people who are known about? Answering these and similar questions, Hacking explores the development of the modern multiple personality movement. He then turns to a fascinating series of historical vignettes about an earlier wave of multiples, people who were diagnosed as new ways of thinking about memory emerged, particularly in France, toward the end of the nineteenth century. Fervently occupied with the study of hypnotism, hysteria, sleepwalking, and fugue, scientists of this period aimed to take the soul away from the religious sphere. What better way to do this than to make memory a surrogate for the soul and then subject it to empirical investigation?

Made possible by these nineteenth-century developments, the current outbreak of dissociative disorders is embedded in new political settings. "Rewriting the Soul" concludes with a powerful analysis linking historical and contemporary material in a fresh contribution to the archaeology of knowledge. As Foucault once identified a politics that centers on the body and another that classifies and organizes the human population, Hacking has now provided a masterful description of the politics of memory: the scientizing of the soul and the wounds it can receive.

"Philosophy and Animal Life" offers a new way of thinking about animal rights, our obligation to animals, and the nature of philosophy itself. Cora Diamond begins with "The Difficulty of Reality and the Difficulty of Philosophy," in which she accuses analytical philosophy of evading, or deflecting, the responsibility of human beings toward nonhuman animals. Diamond then explores the animal question as it is bound up with the more general problem of philosophical skepticism. Focusing specifically on J. M. Coetzee's "The Lives of Animals," she considers the failure of language to capture the vulnerability of humans and animals.

Stanley Cavell responds to Diamond's argument with his own close reading of Coetzee's work, connecting the human-animal relation to further themes of morality and philosophy. John McDowell follows with a critique of both Diamond and Cavell, and Ian Hacking explains why Cora Diamond's essay is so deeply perturbing and, paradoxically for a philosopher, he favors poetry over philosophy as a way of overcoming some of her difficulties. Cary Wolfe's introduction situates these arguments within the broader context of contemporary continental philosophy and theory, particularly Jacques Derrida's work on deconstruction and the question of the animal. "Philosophy and Animal Life" is a crucial collection for those interested in animal rights, ethics, and the development of philosophical inquiry. It also offers a unique exploration of the role of ethics in Coetzee's fiction.

Paul Feyerabend's globally acclaimed work, which sparked and continues to stimulate fierce debate, examines the deficiencies of many widespread ideas about scientific progress and the nature of knowledge. Feyerabend argues that scientific advances can only be understood in a historical context. He looks at the way the philosophy of science has consistently overemphasized practice over method, and considers the possibility that anarchism could replace rationalism in the theory of knowledge.
This updated edition of the classic text includes a new introduction by Ian Hacking, one of the most important contemporary philosophers of science. Hacking reflects on both Feyerabend's life and personality as well as the broader significance of the book for current discussions.

Bringing together important writings not easily available elsewhere, this volume provides a convenient and stimulating overview of recent work in the philosophy of science. The contributors include Paul Feyerabend, Ian Hacking, T.S. Kuhn, Imre Lakatos, Laurens Laudan, Karl Popper, Hilary Putnam, and Dudley Shapere. In addition, Hacking provides an introductory essay and a selective bibliography.
